First plastic cell with working organelle
For the first time, chemists have successfully produced an artificial cell containing organelles capable of carrying out the various steps of a chemical reaction. This was done at the Institute for Molecules and Materials (IMM) at Radboud University Nijmegen. The discovery was published in the first 2014 issue of the journal Angewandte Chemie, and was also highlighted by Nature Chemistry.
It is hard for chemists to match the chemistry in living cells in their laboratories. After all, in a cell all kinds of complex reactions are taking place simultaneously in an overfull, small container, in various compartments and incredibly efficiently. This is why chemists attempt to imitate the cell in various ways. In doing so, they also hope to learn more about the origin of life and the transition from chemistry to biology.
Jan van Hest and his PhD candidate Ruud Peters created their organelles by filling tiny spheres with chemicals and placing these inside a water droplet. They then cleverly covered the water droplet with a polymer layer – the cell wall. Using fluorescence, they were able to show that the planned cascade of reactions did in fact take place. This means that they are the first chemists to create a polymer cell with working organelles. Just like in the cells in our bodies, the chemicals are able to enter the cell plasma following the reaction in the organelles, to be processed elsewhere in the cell.
